Since I know many in the forum share my passion for historical accuracy when it comes to the finer details of flight performance, I want to give a heads-up that there is a new book available with new material to reference when evaluating the in-game flight models we have in CoD. And this book not only covers speed and climb, but also sustained and instantaneous turn performance, dive, dive and zoom and energy retention etc.

Details about the book and what it contains can be found here:https://militaryaircraftperformance.com/ww2-aircraft/
